Examples with PrimitiveType org.hibernate.type.PrimitiveType used on opensource projects

Example 1 with PrimitiveType

use of org.hibernate.type.PrimitiveType in project hibernate-orm by hibernate.

the class ReflectHelper method getConstructor.

/**
	 * Retrieve a constructor for the given class, with arguments matching the specified Hibernate mapping
	 * {@link Type types}.
	 *
	 * @param clazz The class needing instantiation
	 * @param types The types representing the required ctor param signature
	 * @return The matching constructor.
	 * @throws PropertyNotFoundException Indicates we could not locate an appropriate constructor (todo : again with PropertyNotFoundException???)
